Grid PSE builder: a framework for building Web-based distributed PSE on grid

In order to provide a framework for building Web-based distributed PSEs (problem solving environment) on a grid, we have been designing and implementing grid PSE builder. By using grid PSE builder, PSE providers can easily build a PSE using existing large scale scientific-engineering application as PSE components, without specialized knowledge about Web security and programming. On the other hand, PSE user can access the PSE with highly secured way only by using a Web interface. We have built some Web application portals with existing applications by using grid PSE builder as a Web portal toolkit and it is possible to make existing applications into PSE components with only a small amount of work.
